SPECIFICATION forming part of Letters Patent No. 679,396, dated July 30, 1901.

Application filed February 8, 1900. Serial No. 4,550. (No model.)

To alt whom, it may concern.-

.Be it known that I, RASMUS HAGBARTH QUISLING, a subjectof the King of Sweden and Norway, residing at Ohristiansand, in the Kingdom of Norway, have invented certain new and useful Improvements in Time-Fuses for Projectiles; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. My invention relates to combination-fuses for projectiles, (shells 5) and it has for one ob ject the provision of means whereby the firing appliances are locked against action, so that the projectile can be handled and transported with perfect safety. I

The invention has for its further object the provision of means whereby the firin appliances can. readily be released from tne locking device and the timefuse simultaneously timed.

Referring now to the accompanying drawings, Figure 1 is a vertical central section of so much of a projectile as will be necessary to afull understanding of myinvention. Fig. 2 is an elevation of Fig. 1. Figs. 3 and i are sections on lineS 3 of said Fig. 1, showing the locking-pawl in diderentpositions. Fig. 5 is a top plan view; Fig. 6, a longitudinal section; and Fig. 7 arr under side view of a key organized to release the firing appliances and "at the same time time the timefuse, a part of the handle of the key being broken away.

As shown in Fig. 1, the fuse-body 11, which constitutes the conical head of the projectile,

has anaxial chamber intersected at the pointby a transverse chamber in communication with said axial chamber through a suitable aperture in the axial line of said axial chamber. The transverse chamber is in communication with the lower part of tne axial chamber through a passage 12, (shown in dotted line's,) and in said transverse chamber is secured the primer 10. Into the axial chamber above its .lower portion of greater diameteris screwed a supporting-disk for the percussion-hammer or firing-pin 17, whose lower end is of increased diameter and has mounted thereon the concussion-anvil 18, whose conical head 19 cooperates with the concussion-hammer 15 to ignite the priming rings will be communicated to the charge in said chamber 12 through passages 12 and 12. The upper conical portion of the fusebody 11 constitutes the cap, said body being of reduced diameter below said cap portion and screw-threaded at its lower end, and on the smooth cylindrical portion are mounted the fuse-rings 40 and 41., The fuse-ring 10 is keyed to the fuse-body 11, so as to slide longitudinally thereon only, while the timefree ring 41 is free to revolve on said fusebody when not locked or jammed.

The construction of the fuse-body, the fuserings, the percussion and concussion firing appliances, and the arrangement of the primings, so far as I have described them, are well known and,specifically speaking, form no part of this invention, which I will now describe.

Instead of screwing the fuse-body directly into the projectile I provide a sleeve 13, having a flange 13 a short distance from its upperv end, which flange when the sleeve is screwed into the projectile bears upon a shoulder formed by a circular recessin the upper face of said projectile, while the upper or outer end of said sleeve when the fuse-body 11 is fully screwed into the same will bear on the non-revoluble but longitudinally-movable fuse-ring 4:0 and jam the revolubl fusering 41 against the shoulder formed by the conical cap portion of the fuse-body 11 and lock it against rotation.

The sleeve 13 has a notch 27 in its upper or outer portion above its flange 13', while the fuse-body 11 has a longitudinal slot 24, whose lower or inner end wall is in line with the upper or outer face of the supporting-disk 12, while its upper or outer end wall is in line with the lower or inner edge of the head 19 of the concussion-auvil18 and with the like edge of the concussion-hammer 15. The percusr sion-hammer 17 has a foot-flange 16 seated The lever 21 has a nose 2301: a height equal to the length of the slot 24 in fuse-body 11 or equal to the distance between foot-flange 17 ot'percussion-hammer 16 and the head 19 of concussion-hammer 1S,the aforesaid spring acting on the said lever' to project its ,nose into chamber 25, and thus lock the firing appliances against motion, as shown in Fig. 1.

The lever 21 has a lug 26, (shown in dotted lines in Figs. 3 to 5,) adapted to engage the notch 27 in the sleeve 13, hereinbefore referred to, and said lug is of such a thickness as to prevent the fuse-body from beingfully screwed into sleeve 13 when the lever 21 is in its locking position,-so that said fuse body cannot be screwed home, the firing appliances released, and fuse-ring'41 locked against rotation until the lever 21 has been moved against the stress of its spring to withdraw its nose 23 from chamber 25 in the fuse-body 11 and its lug 26 out ofengagement with the notch 27 in outer end of sleeve 13. In order that the'lever may be moved in the manner described, it has-an angular heel 28, that projects into the peripheral recess 29 in fuse-ring 40, the outer end of said heelbeing flush with the outer face of said ring.

\Vhen thefnse-body is to be screwed into sleeve 13, the lever is first moved out of its lockin g position at held there until the lug 26 engages the notch 27 in said sleeve, the lever being then free to return into its locking po sition under the stress of its spring; but owing to the thickness of said lug 26 the fusebody cannot be fully screwed into its sleeve- To effect this and at the same time move the lever 21 into its unlocking position and to time the time-fuse, I employ an implement which I call a key. (Shown in Figs. 6 to S.) The key is composed of a fixed ring 51, having a chambered handle extension, in the chamber of which is revolubly mounted a worm 53 on a spindle 51, provided with a knob or milled head 51 for revblving the same, and on said spindle or formed integral with the worm is a toothed wheel 58, nor mally engaged by a tooth on the free end of a leaf-spring 56, secured in the handle-charm her and locking the worm against rotation. The tooth on said spring is moved out of .engagement with the locking-wheel by means of a push-rod 55, guided by a pin 55, extending through a' longitudinal slot in said rod, as clearly shown in Fig. 8. On ring 51 is mounted to revolve a ring or worm-wheel 52, whose teeth 54 gear with the aforementioned worm 53,-as shown in Fig. 6. The opening in rings 51' and 52 is such as to accurately fit the conicity of the fuse-rings 40and 41 when the key is applied to the fuse-body 11, and

said ring 51 has a fixed lug 61, projecting from its inner periphery and so located that when the key is applied t9 the fuse-body 11 it will engage the peripheral recess 42 in revoluble fuse-ring-41, while the-ring 52 has a lug 6.0, which has radial motion, to which end it is secured to a spring 62, the position of the resilient lug being such as to enter the peripheral recess 29 in fixed fuse-ring 40. The worm-wheel or ring 52 is graduated on its upper face, as shown in Fig. 5, and ring 51 has a segmental slot 51, in which a pointer 59 is adjustable, so that the angular relation of the lugs and 61 can be'varied in accordance with the adjustment of the pointer.

The operation of the key is as follows: .After adjusting the angular relation of the lugs 60 and 61 by revolving the worm-wheel or ring 52 to the required extent and releasing the push-rod 55 to allow the tooth on spring 56 to engage the lock-wheel 58 the key is placed on the fuse-body and fixed lug 61 inserted into recess 42 in the revoluble fusering 41. It has hereinbefore been stated that when the fuse-body 11 is screwed into the projectile-sleeve 13, with the lock-lever 21 in its locking position, Fig. 3, said body cannot be fully screwed into its said sleeve, so as t0 cause its end to impinge upon fuse-ring 40 and cause the latter to jam the revoluble fuse-ring 41 and lock it against rotation. Now when the key is applied",- as described, with the lug 61 in recess 4242f revoluble fuse-ring 41, as stated, and revolved in the proper direction from left to right, Figs. 1 and 3, on the fuse-body, said ring will be caused to revolve until the' resilient lug 6O snaps into the recess 29 behind the heel 28 of lock-lever 21 on the left of Figs. 2 and 3. A further slight rotation-of the key in the same direction will causesaid lug 60 to turn the lock-lever until its nose 23 has been retracted from between the firing appliances, Fig. 4, at which time the lug 26 on said lever will also be clear of the notch 27 in the sleeve 13 above its flange 13', the parts then being i in their relative positions, Fig. 4, and further rotation of the key from left to right becomes impossible by reason of the abutment of the heel 28 of lever 21 against the right end wall of recess 29 in non-revoluble fuse-ring 40. During this rotation of the key the movable fuse-ring 41 has also bee. revolved the required distance, or in ace rdance with the angular adjustment of lugs 60 and 61, and as the lug 26 on lever 21 is now clear of n0tch 27 in sleeve 13 said lever cannot return into locking position and the fuse-body 11 can be fully screwed ontothe said screw to jam and lock the fuseering 41 into its ad usted position, the projectile being now ready for the gun. It will thus be seen that unless the key isapplied to move the lever 21 out of engagement with the firing appliances and sleeve 13 it is impossible to fully secure the fuse-body to or explode the projectile, while the action of the key'not only disen gages the lever from the parts described, but at the same time times the time-fuse.

Having thusdescribed my invention, what I claim as new therein,-and desire to'secure by Letters Patent, is-

1. The combination with the adjustable f use-ring containing the time-circuit of a timefuse forprojectiles, firing appliances for igniting the priming of said fuse, and a locking device for locking'said appliances out of operation; of means organized to operate the locking device to release the firing applitimes and simultaneously therewith revolve the fuse-ring and time the fuse, substantially as set forth. a
